SELF-,ANGHORIhTG PULLER'.

To all whomz't may concern: I

Be it known that we, Gear-ram) Mon and AnrRnD'J. Kms'rm, citizens of the-United States, residing, respectively, atLadysmith, county of Rusk, and State of Wisconsin, and Escanabaycountyof Delta, and State of Michigan, have invented new and useful Improvements in Self-Anchoring Pullers, ofwhich the following is a specification.

The object of our invention is to provide a device for manually pulling an automobile or other vehicle, which has been stalled, disabled, or otherwise prevented from moving by its own power to a desirable place of security. For example, our device is adapted to be used for pulling an automobile from a gutter to a solid roadway,for pulling heav Y boats from the water to a higher level on shore, and for various other similar purposes.

Our invention is further explained by reference to the accompanyingdrawings, in which- Figure 1 represents a side view thereof.

Fig. 2 i a plan view.

Fig. 3 is an end view, and

Fig. 4 is a vertical section a:, w, of Fig. 1. I

Like parts are identified'bythe same reference numerals throughout the several views.

While our device may, as stated, he used drawn on line for moving heavy vehicles, for brevity of description, the same is described as connected with an automobile.

1 represents a cable which is preferably made of wire or other similar material, one end of which, may if desired, be connected direct with an automobile, or such end may be connected with the anchor 2, through the bracket .8; while the central portion 51 of said cable may beconnectedwith an automobile, not shown, atv a distance, through the pulley 5, pulley supporting bracket 6, and cable 7 as shown in Fig. 1; while the opposite end 9 of said cable 1 is adapted to be wound several times around the pulley 7, when its free end 9 may be permitted to rest upon the ground. The pulley8 is revolubly supported from the anchor 2 by the shaft 10, operating in the journal bearing 11,

which is formed integral with said anchor,

' the automobile or otherwise, as clrcumand said pulley 8 is adapted to be revolved by lifting upward upon the hand lever 12. The hand lever 12 is connected with the pe- Specification of Letters Patent.

riphery of the pulley 8 by the eccentric earns 13 and 14:, and said cams are pivotally supported from said lever by the pins 15 and 16 respectively, said cams 13 and 14 being adapted assaid lever i's'moved downwardly to. slideover the contiguous surface of said pulley and cable, without moving the same; while by an upward movement of said lever, said cams are adapted to grip the interior surface 17 and exterior surface of said cable, whereby said pulley is caused to revolve, as indicated by the arrow 19, a partial revolution with each upward movement of the hand lever 12, while said pulley 8 is prevented from being turned back by the wedge shaped member 20, which member is interposed between the periphery-of said pulley .8 and the ball or stopl'21. The anchor 2 is preferably formed integral with the foot lever 22, which foot lever extends rearwardly, a distance corresponding with the length of the hand lever 12, whereby a person operating the hand lever 12 may stand upon the foot lever 22, which has a tendency to hold said anchor securely in place.- To prevent the liability of the anchor sliding forwardly as a tension is put upon the cable 1, we preferably provide a plurality of additional anchors 23, which extend downward from said lever 22 and. are adapted to penetrate the ground and cooperatewith the anchor 2 in holding the device in place, as the automobile is being moved. The anchor 2 is preferably provided atits lower end with a blade 24, which is adapted to be driven into the ground by the strokes of a sledge or a heavy hammer, which may be applied to the upper end of said anchor on the contact bearing 25. The operation of our device is as follows:

The cable 1 being attached to the automobile or other movable object, and the moving device being anchored in the ground, as stated, the pulley'8 is revolved by a succession of upward strokes applied to (the hand lever 12, whereby with each revofzlublemovement of the pulley 8 the automobile or other vehicle will be drawn toward the anchorage until it is brought in the deiasired place upon the solid road or other desired place, when our device is detached therefrom and stored in a suitable place in stances require.

It will be understood that the cable 9 is prevented from slipping upon the pulley 8 as the load is being drawn forward by contact of the eccentric cam 13 which is adapted to rigidly grip the exterior surface of the several coils of said cable, as said lever 12 is raised, whereby said cable and pulley being thus gripped between the cams 13 and 14 are caused to revolve together.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In a device of the described class, the combination of a cable, a cable supporting pulley, an anchor for supporting said pulley, a foot lever attached to said anchor, a hand lever connected at one end with said pulley, a pair of eccentrics attached to said hand lever, said eccentrics being adapted as said last named lever is moved in one direction to pass freely over the surface of said pulley, and as said lever is moved in the opposite direction to grip said cable, whereby the latter is caused to move a partial revolution with each alternate movement of said hand lever.

2. In a device of the described class, the combination of a cable, a cable supporting pulley, an anchor for supporting said pulley, a foot lever attached to said anchor, a hand lever connected atone end with said pulley, a cable connected with said pulley, the grip mechanism connected with said hand lever being adapted as the latter is moved in one direction to pass freely over the surface of said pulley, and as said lever is moved in the opposite direction to grip said cable, whereby the pulley is caused to revolve a partial revolution with each alternate movement of said hand lever, and a wedge shaped member adapted to move with said pulley as the latter is moved in one direction and to grip said pulley and prevent the same from turning in the opposite direction.

In testimony whereof I afiiX my signature in the presence of two witnesses.
